I am new to the forum, and new to breeding, and would really like some help.
I have a 4 week old egg, that was fertile, but looked at it yesterday and the side seems to be collapsing. I candled it, not very successfully, I couldnt see much, meaning it didnt light up well inside, but I did get some orange light. Whats happening ?
I have it in perlite and water, in a tupperware box. that is also placed in a plastic storage box, with a heat mat and thermostat, set at 82 f.
I also have 2, 5 day old eggs, both fertile, in another tupperware box in the home made incubator.
I open the tupperware oxes once a week, for air exchange and to keep an eye on the eggs.
What am I doing wrong ?
Why do the collapse this late on ? Is it normal ?
I'm a little worried because it was doing so well, until now

Hiya, ive never as yet managed leo babies but i do have beardy eggs quite regular, not quite the same but similar, im not sure if they incubate the same, but ive had some that have dimpled and some collapsing at the side at around 40 days, thinking they were somehow bad eggs i wrote them off, then was suprised when babies hatched out of them, if you saw light from inside suggesting that theres still life you should be ok, just keep an eye on them, often when your eggs dimple a tad, this indicates a bit more moisture is needed. When you mist, spray the sides of the container to remoisten but dont directly mist the eggs, im sorry ive not been much help but hopefully someone who has hatched gecko babies will actually offer some advice, ive noticed not many people are offering help at the minute...

Thanks for your reply I have just candled my egg again today, I can now see nothing lit up inside, no yellowing , red or anything, there is no light getting through it at all !
It is only collapsing slightly on the side, there is no mould, and no discolouration of the egg. Has an egg ever been known to hatch as early as nearly 5 weeks ?
